IMPROVEMENT |N.FLVEXTERMINATORS.

The vSehule referred to in these Letters Patent and making part of the same.

' I, AMASK. WALKER, of Hampden, Penobscot county, Maine, have invented certain Improvements in Fly-Exterminators, of which the following is a spcci.-

iication.

Figure 1 is a side elevation;

Figure 2 'an end elevation, showing the''iaps open and Figure 3 an end elevation, showing the flaps closed.

This invention relates toa net vmade'in the shape of a bag, oblong or square in cross-section, and pro vided with flaps at its front end, and witha smaller receptacle at its rear end, the uses of which net, flaps, and receptaclel n'ow proceed to explain. Referring to the drawinga is the net, a very suitable material for which is the coarse ninsliuused for making mosquito-bars, said net being, at its front end, provided with side ilaps b and a bottom ap, c, the side flaps having hooks d, by which, when folded over the mouth of the net, they may be fastened thereto by eyes e', and the bottom flap being furnished with cords f by which it may be drawn up over the mouth 4of the net.

Rings h are secured to the front of the net, at its upper side, through which ringsA a cord, g, is passed, said cords havingz,r hooks, e', fastened to its ends, by

means of which and of hooks 7c, secured. to its lowerfront corners, and of other hooks secured to itsv rear upper corners, the net may be suspended. in a horizontal position either in a room or just outside the door or windowof a room, the lower real' corners bcvreceptacle m, which opens into the net.

inf,r -kept in posit-ion by weights l hung thereto, and the upper front end being kept stretched by hooks o. When the net is thus suspended the flaps should all be open, the lower ap serving to fill that `part of the doorway not occupied by thonet, and thus to prevent the escape of ies. The' `room should then be darkened and the dies therein driven into the net.,

It will be found useful to line the inside of the latter near ,its front end with some white material, as shown the hooks which suspend it unfavstened, and the sides4 of the net brought together gradually from its front toward its rear end, so as to drive all the ies into the. This' being done, the receptacle should be dipped in hot water, so as to kill its occupants- The carcasses-are easily removed from the receptacle by opening its lower end, which is provided witha cord for the purpose.

'lhelaps b, though useful, may be dispensed with, the iap c being thc only one that is absolutely necessarv.

-I claim as my invention'-4 y flhe net a, in combination with the Hap' c andrcceptacle m, as spectlcd.-
